I bet that if you put them in the boutique for maybe 100k bc, they'd get sold
Physical Collector's Editions? Maybe I'm misunderstanding your question, but if you mean real life Collectors Editions, if we had these, they would be sold for real money in an online store. Real life items need to be crafted, stored and have the possibility to be delievered world wide, as well as have the possibility to accept international payments and store information about the personal address of the user where the CE would need to be delievered.
I've seen an unboxing with keychain and other stuff like it, from wwhere it come so ?
There may have been some sold in the past, but currently we don't have any neither for Russia nor Europe/America.
One more question for Lisad, is the wallpaper allowed to be an illustration or is that reserved for the banner? I'll be drawing something regardless but i prefer the larger format if possible.
I'm afraid I don't understand the question. You should basically just draw something that could work as a desktop background.
